AMD is expected to launch the Radeon RX 7600 XT next month to bridge the gap with the RX 7700 XT. We know precious little about the card itself apart from what was revealed by an EEC manifest the other day. The registration data points to a 16GB memory buffer paired with a 256-bit bus, up from the previously expected 12GB plus 192-bit bus. However, given the target resolution and framerates, a 256-bit wide memory bus for a 600-class SKU would count as weird.
The Radeon RX 6600 XT, 6650 XT, and their GeForce rivals feature a 128-bit bus backed by a small cache buffer. Even the RX 7700 XT and the RTX 4070 are equipped with a 192-bit bus instead of a 256-bit solution. Therefore, I’d take this info with a grain of salt.
The shader configuration of the 7600 XT should be beefier than the 7600, which implies using a heavily disabled Navi 32 GPU. The latter already utilizes the fully enabled Navi 33 core. A shader count of 2,560 across 40 Compute Units (CUs) would be a viable option backed by a 40MB “L3” cache buffer. The core clocks should be the same as the existing RDNA 3 parts with a TBP of roughly ~200W.
The Radeon RX 7600 XT is expected to launch on the 22nd of January at an MSRP of $349 alongside the RTX 4070 Ti Super.
